I am facing some strange problem. I compiled the latest linux kernel and used "make localmodconfig" to create my .config file. In the new kernel "ping" does not work. However the following works. NSLOOKUP works, DIG works, host works. Similarly giving ifconfig after "ping" shows increase in TX and RX counters. So it looks to me like packets are received. SELinux is disabled and iptables does not have rules.

Contents of /etc/resolv.conf


Ping by IP works. For example, if I ping the IP address of google, I am getting response. The name servers are also pingable.

Can someone please help me out.

Sounds like nsswitch.conf may be incorrect. – David Schwartz Jul 1 '14 at 23:13
Is it just which gives you a problem or you can not ping other places as well? – Nikolay Jul 1 '14 at 23:24
Any address with host name cannot be pinged. If I "nslookup" the host name and ping the IP, I am able to ping. Curl / wget also does not work – CHID Jul 2 '14 at 19:08
@DavidSchwartz : Thanks. I went over a couple of forums which suggested the issue could be in nsswitch.conf. Unfortunately my file is same as specified in those forums. – CHID Jul 2 '14 at 19:08
